Gordon Sumerling looks at the challenges of mixed data using different datums, and how to avoid alignment issues.
GDA2020 service packages
GDA2020, Australia’s new official datum, will align the country’s national coordinates with global satellite positioning systems, enabling smart devices and other positioning technology to accurately locate mapped features.
Failing to update location data to GDA2020 risks exposing discrepancies of up to 1.8 metres relative to GDA94-mapped features. That’s why you need a strategy and workplan built on a thorough analysis of your requirements.
